Application filed Sinne 11, 1920. Serial No. 388,256;

To all whom it may concern:

Be it'known that 1, WILLIAM SUNDBERG, a citizen of the United States,and a-resident of'Chicago, county of Cook, and State oflllinois, haveinvented a certainnew and useful Grain-Door-liemoving Device, oiwliich'the following is a specification.

My invention relates to improvements in means for removing the inner, orgrain door from a box car, said'door being commonly fastened at thesidesand on the inside of a box car as by means of nails. When the term graindoorsis used in this specificati'on it refers to the inner door of aboxcar, whether the car be" loaded with grain, coal or any othermaterial which is shipped in bulk form in box cars.

By the means now. in general'use for re moving grain doors, a sledge orhammer is used to knock the grain door loose. This not only takesconsiderable time, but also considerably damages the grain door so thatit must be repaired before it can be used again.

The objects of my invention are, first, to provide a means for quicklyremoving a grain door from a boX car; second, to provide a means forquickly removing a grain doorfroma boxcar as by mechanical means andwithout materially damagingthe said grain door; third, to provide ameans for removing grain doors which can be used in conjunction with, orwithout, the unloading machine which is described in myapplicationfS'erial Number 331,561, filed October companying drawings asbeing attached to the before mentioned unloading machine, can of course,be used independently, that is to say, this device can be used as aseparate and distinct device for removing grain I doors.

One form of iny inventionis shown in the drawings, in which Flg. 1 saside elevation of the door remov ng device, 1t being shown Iasat-tached to the unloading machine, a general outline of the unloadingmachine also being -shown.

'2 is a v of the pry-0E members. 7 y

Fig. 3 isa'plan view taken substantially on line of Fig.1, a generaloutline of the unlbadingmachine also being shown.

fdi'eterring tothe drawings, the side i'rame front elevational view ofone castings 45 and 46, shafts 99,104c and105,

and angle50 are all part ofthe unloading machine as described in my saidapplication, Serial Number 331,561.

The door removing device consists of they following parts two pry-offmembers, 1 and 2,jeach of which iscomposed of two channels, saidchannels being separated asby means of a pluralityof plates, 3, andbeing fastened together as; by means of bolts or 3 rivets. Attached toand extending out from each of the pry-off members 1 and 2, areaplurality of sharpened pins, 8.

' Links 1 and 5 are each pivotally mounted at one end on sl aft 105, andat'the other end i are pivotally mounted on'pins 6 and? carried by therespective pry-off members 1 and 2, said last mentioned end of the links4: and V i 5, respectively, being placed between the two channelsofwwhich the pry-oil? members 1 and 2 are composed, the" pins 6 and T,re-

spectively, passing through each pair of channels as shown'and beingheld in place as by means of cotter pins.

Bell crank levers 9 and otally connected atone end to pry-0E Incinvers 1and 2, respectively, as by means of 10 are each pivpins 11' and 12,said'pins passingthrough each pair of channels and being held in placeas'by means of cotterp'ins. which levers 9 and-10' are mounted; servesas a fulcrum for thesaid lever-s. Collars 13, 1st, 15 and 16 servetohold links 4: and 5,

and; levers- 9 and 10;,r espectively, in place on shafts 105 and 10 1-,said'shafts extending out fromcastings 45 and 46 iarenoughtoaccommodatesaid collars, -links and levers. Sheaves 17 and 18 areattached to angle 50. as shown, said angle extending out fromframecastings 45 and- 16 far-enough to acco'mmodate said'sheaveslfLooselymounted on. shaft 339' are ,drunis Shaft 104, on=- 19 and 20,each of which is' fitt-ed with a I friction'clutch 21 and 22,respectively. A.

rope, or cable, 23,one end of which is fastened to drum 19, passes oversheave 1.? and has its other end iastenedlto the upper end of lever 9. Asimilar rope, 24-, connects drum 20 to lever 10., i

The operation of thedoor removing device isas follows: The operatorbrings the unloading machine to the-front of the door, 25, which is to'be removed from the .car 40.

Then he throws clutches 21 and 22 in, thus .means of cotter pins.

causing ropes 28 and'24 to wind up on drums 19 and 20, respectively, andcausing levers 9 and 10, links 4 and 5, pry-off members 1 and 2, anddoor 25 to take the position shown by dotted lines, the grain door 25thus being pried loose.

The pins, 8, grip the door, 25, and hold same- When the pry-oft membersare in the position shown. by dotted lines, the operator throws clutches:21 and 22 out, the pawls 34 and 35, which engage the ratchet facedflanges of drums 1.9 and 20, respectively, preventing the pry-oilmembers, against which door 25 is held, from dropping.

V The grain or other material with which the car is loaded thuspermitted to flow out oi the car from the sides and under the door. 1Vhen the grain which is in front of the door has flowed out of, the carby gravity,

the operator lifts the pawls 34 and 35, thus allowing pry-oft members 1and 2 to drop to the position shown by full lines and jarring door 25loose from the said pry-off members. The operator next removes the doorfrom the car and the remainder of the contents of the car may be removedby any desired. means, for example, by the unloading machine describedin my said applica tion, Serial Number 331,561.

Links 4 and 5, which rest upon the upper angular face of lugs 28 and 29,said lugs being part of castings 45 and 46, respectively, preventpry-off members 1 and 2 from droppin below the position shown by fulllines. lry-ofl? members 1 and flare prevented trom falling backwardtowards the machine when in the position shown by full lines, because0:1? lugs 86 and 37, said lugs projecting out from and being part ofcastings 45 and 46, respectively, the pry-off mem 'bers resting-againstsaid lugs.-

To prevent the unloading machine from backing up when. pressure isapplied to the grain door 25,pawls 30and 31 are provided, sald pawlsbeing placed between castings and 46, respectively, and being mountedon. pins 82 and 33, respectively, said pins passing through castings 45and 46, re spectively, and' being held in place as by Notches' are cutin rails 318 and 819, pawls 30 and 31 engaging these notches andpreventing the machine 1 from backing up. 'l/Vhenpawls'BO and 31 are notin use they can be held in the position shown by dotted lines by catchmembers Q6 and 27 adapted to'hook overcastings 45 and 46, respectively,as shown. v

Inasmuch as this disclosure will suggest to others, various modifiedstructures and mechanisms whereby the substantial objects and purposesof my invention may be attained, I do not wish to be limited tothe exactconstruction shown and'described.

, I claim'as my invention. v
